to the combination of an improved radiator construction with a wall construction for receiving the same.

As is well known to those skilled in. the art, heat radiators of the usual constructions are very unattractive in appearance and form unsightly conspicuous obstructions along the wall space which seriously interfere with the decorative scheme of a room. It has been attempted to obviate this objection by concealing the radiators by means of ornamental covers and in other ways. This is unsatisfactory since the covers interfere with the transmission of heat and the radiator with the cover applied still has the disadvantage that it constitutes a conspicuous obstruction extending out from the wall space.

One object of the present invention is to produce a radiator which will present a highly attractive and ornamental appearance, and

. will blend with the decorative scheme of the 26' walls of the room in which it is placed.

Another object of the invention is to produce an improved radiator construction and a wall construction for receiving the same so that the radiator does not constitute an un- 30 sightly obstruction to the wall space, and the radiator will function efficiently in the transmission of heat.

Still another object of the invention is to improve the construction of heat radiators 85 and to produce a radiator which may be manufactured at a reduced cost as compared with prior constructions.

With the above and other objects in view,

the invention consists in a radiator embodying the novel and improved constructions, arrangements and combinations of parts hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art.

The invention will be clearly understood from the accompanying drawings, illustratmg the invention in its preferred form and the following detailed descri tion of the constructions therein shown. 11 the draw- [0 1ngs Fig. 1 is a view in front elevation showing a portion of a wall of a room and radiators embodying the present invention applied to said wall;

Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a sectional view taken substantially on'the line 3--3 of Fig. 1;

Fig. 4 is a view in front elevation with certa n parts broken away, illustrating the radiator construction shown in Figs. 1, 2 and 3;

Fig. 5 is a view in front elevation illustrating a modified form of the invention; and

Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 5.

In the construction shown in Figs. 1 to 4 inclusive, the radiator indicated as a whole at 2 comprises a rear wall 1 and a front wall 6 united at their u per, lower and lateral edges 8 and spaced From each other between these edges except at certain points. The rear wall of the radiator is preferably corrugated so as to present a relatively large heat radiating surface. The front wall 60f the radiator is made in such a form that when the radiator is applied to the wall of a room with the wall 6 of the radiator outermost, the latter wall will blend with the wall so of the room, or at least will present a highly attractive appearance.

' As shown in Figs. 1 to 4 of the drawin the outer wall 6 of the radiator is made in t e form of a number of panels indicated at 10 35 of the same size and shape as panel 12 formed on or applied to the walls of the room. The front wall of the radiator is formed with portions 14 surrounding the panels and forming the borders thereof, which portions have a maximum spacing from the wall 4. The wall 6 is formed with portions 16 constituting the central portions of the panels which are spaced a distance considerably less from the wall 4 than the portions 14. Within the portions 16 are formed rooves 18 in the wall 6 and the parts of said wall at the bases of these grooves preferably contact wlth the wall 4 as is clearly shown in Figs. 2 and 3.

By the combination of the corrugated rear wall 4 and the panelled front wall 6, a series of passageways are formed between sald walls which tend to produce an efiicient circulation of the fluid within the radiator.

The front and rear walls 4 and 6 of the radiator are preferably made of separate sections of sheet metal, and the marginal portions ,of the respective sheets constituting these walls are preferably welded together. The front wall 6 is also preferably welded to the rear wall 4 at the points along the bases of the corrugations 18 at which the front wall contacts with the forwardly projecting portions of the corrugations in the rear wall. This forms a strong, rigid structure which will efficiently withstand any interior pressure to which the radiator is subjected when in operation. In actual practice, radiators having the front and rear walls formed of sheet brass welded together in the manner described, have been found to give highly satisfactory results.

Radiators of the character described may be heated by a circulation of steam or other heating fluid through the same. When heated by steam, the steam is preferably introduced into the radiator through the inlet pipe 20 and is discharged through the outlet pipe 22. Radiators of this character may also be heated by means of an electrical heating unit immersed in a fluid within the radiator. When heated electrically, the outlet ipe 22 is closed and the wires leading to the heating unit pass into the radiator through pipe 24 at the base of same. The radiator is filled with fluid through the pipe 20 so that the heating unit is entirely covered by the fluid. This pipe is then closed by a suitable plug.

The radiator is preferably mounted in a recess 26 in the wall of the room in which it is used, as shown clearly in Fig. 2. This recess is preferably made somewhat deeper than the full thickness of the radiator and the radiator is inserted in the recess so that the flange at the marginal portions 8 of the radiator engage the wall at the margins of the recess, as shown in Fig. 2." This locates the radiator so that the portions of the outer face having the maximum spacing from the inner wall of the radiator are flush. with the outer surface of the wall of the room and leaves a space at the inner portion of the recess for air circulation.

In order to provide for the circulation of air through the recess at the back of the ra- With this construction, the heated air be- I bind the radiator rises and passes out through the screen 28 into the room and its place is taken by the air entering the recess through the screen 30.

Figs. 5 and 6 show a somewhat modified construction. In the construction shown in these figures, the front wall of the radiator is formed with a single panel and is provided with extensions 32 and 34 projecting beyond the body of the radiator so as to cover the extended portions of the recess 26. Extensions 32 and 34 are formed with perforations 36 to provide for the circulation of air through the recess.

The above radiator construction has resulted in a considerable reduction in the cost of manufacture. Radiators of this construction mafy be manufactured by cutting two sections 0 sheet metal, such as sheet brass, to theproper size, passing these sections through stamping presses to reduce the same to the proper cross-sectional form, placing the two sections face to face and welding the same together along their margins and at desired-points within-the marginsf Instead of being inserted in a recess in the wall, radiators such as described above may be applied to the plain surface of a wall. When so applied to the wall, the radiator is preferably spaced a short distance from the wall so as to provide for air circulation be tween the wall and'the radiator.

Radiators of the above construction do not form unsightly obstructions along the wall space of a room but will harmonize and blend with the decorative scheme. Where the wall of the room is paneled and the front wall of the radiator is given a panel formation corresponding to the panels of the room, the presence of the radiator will not be evident to the ordinary observer and will be indicated only by the air circulation screens above and below the same. Even when there 1s no room paneling and when the radiator is not mounted in a recess in the wall but is applied to the plain face of the wall, the panel form of the front wall thereof will render it much less conspicuous and objectionable than the ordinary radiator and will appear, at a distance, as an ornamental element of the wall space.

Having thus described my invention, what is desired to be secured by Letters Patent of the United States, and claimed is:

1. A radiator construction comprising a rear wall, a panel-formed front wall having a border portion spaced from said rear wall,

' tions, the intermediate and central portions being substantially parallel with the plane of the border portion.

3. A radiator construction comprising a rear wall and a panel-formed front wall, each panel having a central portion and two or more portions parallel to the outer margin of the central portion and surrounding the same and located in different spaced relation to the rear wall, one of the latter portions constituting a border portion for the panel.

4. A radiator construction comprising a sheet metal front wall having a panel formation and having its marginal portions extending in the general direction of the general plane of said Wall, and a sheet metal rear wall having respectively inner and outer portions spaced at different distances from the corresponding portions of the front wall and its marginal portions extending in the general direction of the general plane of said rear wall, the inner faces of said marginal portions of the front and rear walls being arranged in contact and said marginal portions being welded together to form a fluid tight chamber.

5. A sheet metal radiator construction comprising a sheet metal front wall having a panel formation, each panel comprising a central portion and intermediate and border portions substantially parallel to the margin of said central-portion, certain of which portions are arranged at different distances from the rear wall, a sheet metal rear wall arranged in face-to-face relation to said front wall and having the inner face of its marginal portion contacting with the inner face of the marginal portion of said front wall, the marginal portions of said walls being welded together substantially about the entire margins ofsaid walls to form an enclosed space for a fluid medium.

6. A sheet metal radiator construction having in combination, a sheet metalv front wall having a panel formation, each panel comprising a central portion and intermediate.

and border portions substantially parallel to the margin of said central portion, certain of which portions are arranged at different dis-' tances from the rear wall, a sheet metal rear wall arranged in face-to-face relation to said front wall and secured to said front wall substantially about the entire marginal portions of said walls to form an enclosed space for a fluid medium.
